The reason why the government will implement this, as a precaution, is to protect people from losing their wealth and their health from too much gambling because of addiction, it's a way of protection.
The government would never do that, they act like the care while they don't, those casinos will lose customers if this get implemented and that'll be bad for business, if there's no business then the government don't get paid.
The casinos are one of the businesses that the government get taxes from because they're actively making profit. The government won't want to lose that tax revenue. The casino aren't responsible for your addiction too.
You should be able to control yourself and only bet with money you can afford to lose, if you can't handle your addiction then quit gambling and look for other ways you can make money or entertain yourself that isn't gambling.
I think it depends on the government we are talking about. Keep in mind the more centralized a government is, more bureaucracy and regulations they like creating and enforcing, because after all, it generates more jobs' spots for new regulators on the public administration, what allow the government to employ their campaign's supporters (working as a reward for the support and votes received to win the polls).
The theory presented by OP is an interesting one, and I don't think it's totally impossible to happen for real. It will depend on the course modern society or some countries in particular take from now on.
